I saw that this website (https://solarbright.energy) has very good deals, but I suspect they are a scam.
Why:
They have a UK phone number that nobody answers, I got a very defensive response when I asked too many questions, seems "too good to be true", says they support Paypal, but checkout system doesn't forward to Paypal, no social media, no verified TrusPilot company info, etc
But maybe I am wrong?
